Fire resistant drywall is made with glass fibers in an extra-thick design. This makes them ideal for use in utility rooms, garages and areas near a furnace or wood stove. Prevents the spread and speed of fire. Generates less smoke than traditional drywall.
What thickness drywall should I use in my garage?
The most common drywall panel size measures 4 feet by 8 feet, and if the garage walls are 8 foot high, that's the optimal size. If the garage walls are 9 feet high, select panels that are 54 inches wide.
What kind of drywall do you use for garage walls?
For the majority of your garage, you can use standard 1/2 inch drywall. For the ceiling and wall abutting the house (if this is an attached garage), you should use 5/8-inch sheetrock or type X fire-rated drywall.
